For the past 2 days I've been exhausted. Between the very cold wind we've had today and yesterday and temps and my arthritis that's been acting up since the beginning of the year I am beat. My knees , shoulders and hips have been acting up today, which only makes it worse. I read last night that oa can weaken my muscles at some point. I haven't gotten that bad as of yet thank goodness just the constant aching in my joints. So I'm going to relax as much as,I can over the weekend and try not to over do it. When I'm tired my osteoarthritis acts up. Hopefully my feet, ankles, knees and shoulders won't hurt over the weekend. I'm keeping my fingers crossed.
